Ball mill - WikipediaA ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow.difference between ball and tube mill,difference between ball and tube mill,Ball, Rod, and Tube Mills IThis differ- ence in capacity is due to the difference in the weights of the respective grinding charges used in these two types of mills.
